Setting aspect ratio in FCP5

Hi there. Dumb question from a novice editor.
I have just started editing with Final Cut Pro 5 and I am capturing video shot on a Sony DSR450 WSPL set to 14:9 wide mode. However, the windows in Final Cut are displaying it in 4x3 mode. Is there a tweak somewhere to display it in the correct aspect ratio?
Cheers, Chris.
